Lab Five: Circular Motion Purpose: In this experiment, our goal is to verify that centripetal acceleration and force are radially inward towards the center of the center of their circular trajectory. Also, our goal in this experiment to verify that centripetal acceleration is equal to v 2 /r and that centripetal force is equal to mv 2 /r. Data and Calculations: **For this lab, I was not able to be present because I was sick during the day of the lab (bronchitis). For this reason, the data used in my calculations was of the data that of Bryce Hediger, Owen Dennis, and Lisa Logel collected on 5 February 2008.
